I finally have OsTIrus working great and now there is a new update with what appears to be a lot of bug fixes and stuff so I think I should update, but I'm worried it will screw up things I have working now (the proper Virus Ti skin especially). Do I uninstall first and then install the update as new or what is the easiest and most painless way to update this, in steps if you please

Thanks friends!

 

No one's forcing you to update. Aswell as backing up your current version in case you gotta roll back.

So, if you feel for it, try it. No need to overwrite it immediately.

As for myself, I have no problems with the new updates and my saved projects, but not everyone is 'lucky' so taking my word for it is not the same as a "yes, it is safe" as long it's still in a Beta phase.

 

You can simply overwrite the file "OsTIrus.vst3" using copy and paste:

OsTIrus.vst3

C:\Program Files\Common Files\VST3
C:\Program Files\Common Files\VST3\OsTIrus.vst3

Your settings have already been saved with the DAW.

As @PulseWave says, the plugin folders are in those locations.

Only the "OsTIrus.vst3" & "OsTIrusFX.vst3" folders need be replaced.

The skins, ROMs,etc SHOULD be in your user Documents\The Usual Suspects\OsTirus| folder, safe from meddling.

 

You can safely update Ostirus by overwriting the VST3 with the newer version, everything else should be saved in your document folder and you can always have an extra copy of the previous version to roll back to if you have any update issues, you won’t lose any progress saved in your workstation
